Thank you for that

I have never seen a compressor lock up the engine

not saying it can not happen

but my thoughts are the compressor head gasket blew

and leaking coolant into the cylinders, that would be the white smoke

and coolant on the piston hydraulic lock

I suggest to loosen the exhaust manifold and see if the coolant

is there

I hope this helped you

Basically means if happens the case the engine won't turn over?
Expert:  Wayne replied 8 months ago.


if you get coolant on top of pistons , no it will not turn over

get a screwdriver or bar and try to bar engine over back ward

see if it moves
